Larvicidal potential of copper sulphide nano aqua dispersions against Aedes aegypti (Linnaeus)
Nanotechnology has emerged as promising field in insect pest management. Aedes aegypti (Linnaeus) a well-known vector of dengue, chikungunya, and dengue haemorrhagic fever has no commercial management practice for their eradication at the larval stage. In the present study, copper sulphide one of the most detoxified form of copper with biopotential properties was synthesised by standard methodology using sonochemical irradiation method and was evaluated for their larvicidal potential against Ae. aegypti. Treated larvae were observed for various morphological changes as compared to control. Larvae were most susceptible to CuSNPs at 7 ppm showing 100% mortality within 24 h. LC50 and LC90 values calculated with the help of POLO software were 4.42 and 5.73 ppm. The epithelium layer of treated larvae was damaged as compared to control. Remarkable results of copper sulphide nanoformulations at low dosage against Ae. aegypti larvae advocates their further exploration for vector control programmes.
期刊介绍：
African Entomology (ISSN 1021-3589 – print / 2224-8854 – online) replaced the old Journal of the Entomological Society of Southern Africa in 1993. A single volume consisting of two issues (March and September) is published annually. The journal is indexed in all major abstracting journals
African Entomology is a peer reviewed scientific journal that publishes original research articles and short communications on all aspects of entomology, with an emphasis on the advancement of entomology on the African continent.
